Full-hard ASTM B617 vs. Full-hard Type 2 Magnetic Alloy

Full-hard ASTM B617 belongs to the otherwise unclassified metals classification, while full-hard Type 2 magnetic alloy belongs to the iron alloys. There are 18 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is full-hard ASTM B617 and the bottom bar is full-hard Type 2 magnetic alloy.
